A method comprises: determining whether an external wireless power (EWP) source is coupled to an interface configured to transfer power from the EWP source to the power management (PM) system; selecting the EWP to power the computer mouse when the EWP source is electrically couples and provides power to the interface; determining whether a fixed internal power source (PS) is coupled to the PM system; selecting a fixed internal PS to power the computer mouse when the fixed internal PS is coupled to the PM system and the EWP source is coupled to but not providing enough power to the interface; determining whether a removeable internal PS is electrically coupled to a PM system in the computer mouse; and selecting the removeable internal PS to power the computer mouse when the removeable internal PS is electrically coupled to the PM system and the EPS is not coupled to the interface.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The computer mouse of claim 1 wherein the removable first charge storage device is a removable battery, and wherein the first charge storage device is determined to be electrically coupled to the MUX when the first charge storage device has a voltage supply level above a threshold value.
3. The computer mouse of claim 1 wherein the interface is configured to receive a removable modular insert that, when inserted into the interface, enables the computer mouse to wirelessly receive power from the external power source.
4. The computer mouse of claim 3 wherein the external power source is a charging mouse pad configured to wirelessly provide power to the interface via electromagnetic induction when the computer mouse is placed on or near the charging mouse pad.
5. The computer mouse of claim 1 wherein the second charge storage device is a supercapacitor.
6. The computer mouse of claim 1 wherein a total allowed current supplied by the external power source is between 40-60 mA, wherein the external power source is configured to simultaneously provide power to the one or more processors and charge the second charge storage device without exceeding the total allowed current.
8. The method of claim 7 wherein the removeable internal power source is a removable charge storage device, and wherein the removeable internal power source is determined to be electrically coupled to the power management system when the removeable internal power source has a voltage supply level above a threshold value.
9. The method of claim 7 wherein the external power source is a charging mouse pad configured to wirelessly provide power to the power management system via electromagnetic induction when the computer mouse is placed on or near the charging mouse pad.
10. The method of claim 7 wherein the fixed internal power source is a supercapacitor.
11. The method of claim 7 wherein a total allowed current supplied by the external power source is between 40-60 mA, wherein the external power source is configured to simultaneously provide power to the power management system and charge the fixed internal power source without exceeding the total allowed current.
13. The system of claim 12 wherein the removeable internal power source is a removable charge storage device, and wherein the removeable internal power source is determined to be electrically coupled to the power management system when the removeable internal power source has a voltage supply level above a threshold value.
14. The system of claim 12 wherein the external power source is a charging mouse pad configured to wirelessly provide power to the power management system via electromagnetic induction when the computer mouse is placed on or near the charging mouse pad.
15. The system of claim 12 wherein the fixed internal power source is a supercapacitor configured to be charged by the external power source via a charging circuit.
